在启动zookeeper后jps查看并没有zookeeper进程，确定其他文件没有问题后
ZooKeeper JMX enabled by default
Using config: /opt/module/zookeeper-3.4.10/bin/…/conf/zoo.cfg
Error contacting service. It is probably not running.
1、查看zookeeper.out
nohup: 无法运行命令"/opt/module/jdk1.8.0.144/bin/java": 没有那个文件或目录
2、查看java -version
发现java version从1.8.0.144变成了1.8.0_282
卸载后重新安装即可正常启动
rpm -qa|grep java sudo rpm -e --nodeps java-1.8.0-openjdk sudo rpm -e --nodeps java-1.8.0-openjdk-devel sudo rpm -e --nodeps java-1.8.0-openjdk-headless
